Most crayons are made of petroleum paraffin wax. Crayon Rocks are made from U.S.A. grown and processed soy wax. We combine this wax with other plant waxes and a variety of non-toxic powdered pigments to create beautiful colors. We use a natural ground rock to give the crayons their body. This creates a crayon that goes on smooth and blends easily and is, in many ways, much like an oil pastel.

And then a couple of engineering nerds (Edwin and Andrew) from Stanford University School of Engineering in San Francisco built us a machine we named Daisy. She spits out 14,000 crayons a day with only a little supervision from her dedicated handler. And in 2010 we moved from the hustle and bustle of California to the quiet rural peace of Kentucky Amish farm country. We work in a beautiful 4,000 square foot shop that my exceedingly wonderful Plain People neighbors built for me at the bottom of my hill in Hestand.
